Characteristics Generating Ideas

Good The manual discusses the instrument’s history and development as well as: its definition and purposes, theoretical rational, and validity and reliability evidence. Norms are discussed with little information about the normative group of over 2000 high sch

Fair Only a discussion of face validity is offered. Little evidence is given for the validity of the subtests. Correlations with grades is .63.

Fair Reliabilities are variable on CAB-5 .43 to .87. There is some indication of inflation on several CAB sub-tests.

Fair CAB-5 can be administered by any professional to groups. It is timed and takes about 1 hour with instructions. It is scored locally by hand. Answers are placed in the test book. Items call for verbal and drawing responses. Scoring instructions are confused.

Fair Standard Errors of Measure are reported but other score interpretation information is lacking.

Poor Not addressed in the manual.

Reviews & Related Lit
TiP V, 1999; MMY #9, 1985: Nichols, R C. states that the manual is greatly in need of revision. White, K. R. “ From the data that are available, some of the subtests included in the CAB are not well established ...most reliability estimates are inappropriate for speeded tests ... and validity data are sparse and sometimes logically inconsistent. If additional data were collected, many of these problems might be solved.”
